Process for completely exploding high explosives.



HANS VON DAHMEN, OF VIENNA, AUSTRIA-HUNGARY.

PROCESS FOR COMPLETELY EXPLODING HIGH EXPLOSIVES.

Specification of Letters Patent.

Patented April 24, 1906.

Application filer. May 2,1905- Serial No. 258,508.

To (LN whom, if may concern:

Be it known that l, Iiaxs VON Dannnx, a subject of the Emperor ofAustria-liungary, residing at Vienna, in the Empire of Austriallungary,have invented new and useful Improvements in Processes for (ompletelyExloding High Explosives, of which the folowing is a specification.

In my United States Letters Patent No. 689,577 it is stated that thealuminium explosives therein described can only be com pletely explodedby means of strong fulminets of mercury preparations. As, however, theemployment of such highl '-explo sive bodies, especially in the casehollow grojectiles, is attended with considerable anger, I haveconducted experiments with a view of replacing the said preparations bless dangerous or harmless materials. have now ascertained that theexplosives disclosed in my said Letters Patent can be pressure into agaseous state.

'caused to explode completely by means of gunpowder provided that theyare inclosed m very strong resistant projectiles or in strong fusesscrewed into the pro'ectiles and that materials are rovided which act asexciter to convert tie explosive under high Such materials as lastmentioned may consist, for exam is, of a mixture of lead peroxid,sulfur, car on and potassium nitrate in the proportions oi 4.5 to l to2.5 to 5.5. Each of these several ingredients is very finely pulverizedand then all intimately mingled in a mixingdrum, whereupon the are addedto the explosive, consisting o ammonium nitrate, orty-five per cent.;'di or tri nitrotoluene, 19.5; aluminium, twenty-two per cent. Theresultant composition can now be pressed or 40 ranulated or may be usedin pulverized Ol'lll.

For filling hollow projectiles the composition should preferably begranulated. For filling fuses the powdered condition is preferable. Inany case ignition is effected by means of gunpowder.

To ignite the explosives disclosed in my said Patent No. 689,577 bymeans of a fuse, the hollow projectile is first filled with theexplosive and a tube or cylindcr closed at one end filled with thepowdered compose tion above described and iirmly screwed toa suitableunpowder fuse, then introduced into the hollow. rojectile.

Having thus i escribed my invention, what I claim as new, and desire tosecure by Letters Patent of the United States, is-

1. .The process of completely ex loding aluminium explosives or all highexp osives, picric acid, guncotton, &c., consisting in mixing theexplosive with lead peroxidfsuh fur, carbon and potassium nitrate andfilling the whole into a strong container, and applying gunpowderthereto as igniter, substantially as described.

2. The process of completel ex loding aluminium explosives or all bigexp osivcs, picric acid, guncotton, &c-., consisting in mixing theexplosive withlead peroxid', sulfur, carbon and potassium nitrate,placing the composition in a tube closed at one end, affixing agunpowder-fuse at the other end of the tube, and inserting the fuse withthe tube below into a projectile previously filled with the saidexplosive, substantiallyas described. In testimony whereof I have signedmy name to this specification in the presence of two subscribingwitnesses.
